Lucy Mecklenburgh and Jessica Wright became involved in a violent on-set argument, according to claims made in The Sun.
Jasmin Walia was allegedly injured during the fight while the show was filming on Wednesday (June 5).
"The row was getting out of hand and way beyond the usual handbags that go on on the show," a source claimed.
"A producer decided he had to act and dashed in to break it up."
Producers reportedly decided not to air the row during last night's (June 9) episode on ITV2.
An ITV spokesman said: "While our investigations continue, producers have informed Jessica and Lucy that they will not be filming."
Mecklenburgh recently spoke to Digital Spy about her split from co-star Mario Falcone, saying he did something "worse" than cheating.
